Abstract

Current spectrometers are unsuitable for measuring transmission of large thick electro-optical windows because the optical path through the instrument is changed by the optic. Customization of a standard FTIR spectrometer capable of making normal and non-normal incidence angle transmission and reflection measurements is presented which addresses this and other problems associated with high precision spectroradiometry. Emphasis is on design features to ensure ordinate accuracy of these measurements. These techniques can replace witness sample testing commonly made in the industry.
